To all whom it may concern Be it known that we, CLAY L.v HOFFMAN and \VILLIAM E. S'ro vn'n, citizens of the United States, residing atzPort'smouth, in the county of Scioto and State of Ohio, have invented certain new and useful Improve" ments in Safety. Metallic Railroad-Ties, and we do hereby declare the following to be a full, clear, and exact description of the invention, such as willlenable others skilled in the art to which it appertains to make and use the same. I

An object of this invention is to provide a metallic rail tieembodying all of the desirable characteristics of the ordinary wooden tie, mcludlng its res1l1ency,and one which may be inexpensively manufactured.

WVith these and other objects in view the invention consists in the construction and arrangement of parts as are hereinafter specifically set forth in the specification and illustrated in the accompanying drawings,

representing an approved and practical embodiment thereof, in which,

Figure 1- represents a perspective view of the tie partly broken away, as applied to use. Fig. 2 represents a transverse sectional view therethrough. Fig. 8 represents a longitudinal central sectional view partly broken away, and, Fig. 4 represents a bottom plan view of the tie partly broken away.

Referring to the drawing more in detail, the numeral 8 indicates a pair of angle bars L-shaped in cross section and arranged oppositely as most clearly shown inFig. 2. The bases or horizontal portions 10 of the angle bars are formed at their abutting longitudinal edges with a series of interfitting projections and depressions adapted to prevent relative longitudinal movement of these parts. The vertical portions of the adapted to receive the base and a portion of the web of the rails12; It will be understood that the openings 11 for each bar 8 are formed a distance apart, representing Specification of Letters ratent.

. The inner walls 13 'of'the vertical portion ofathe' anglebars 8 are inclined upwardly toward each other so as to provide a substantial dovetail groove forthe reception of occupy the enlarged upper 'ends of the recess '11 in the bars 8 ,and their adjacent UNITED 4 onAYn HOFFMAN A D WILLIAM E. srolvi nf orfronrs vrourn, onro; 7

'thesimilar shape body of the rail engaging members 14 which are arranged in pairs faces are shaped (as clearly shown in Fig.

to receive and snugly fit the base and web of the contiguous portion of the rail 12.

'The upper surfaces of the bases 10 of the angle bars are concave when the bars comprising a pair are'united, while the bottomfaces of the members 14: are plain, thus leav-. ing the space indicated by the numeral 16 in Fig. 2 the purpose of which is to increase the resiliency of the'tie. 1 1 i A pairof-angle bars 8 comprising each tie I cooperating nuts 18,. and it will .be under- I stood that the number and position of these I bolts may be varied in accordance with the are suitably secured together by bolts 17 and weight and character of the load imposed upon the .rails of the track. Springs 19 are positionedover the bolts and between the adjacent walls of the vertical portion ofthe angle bars 8 and further increasing the re siliency of the tie. In use, it is desirable to set the greater portion of the tie in the railway road bed as in this way the ordinary and objectionable rattling and rumbling incident to the travelof the cars thereover is eliminated.

What we claim is I g 1. A railway tie comprising a pair of oppositely arranged J angle bars having oppositely inclined inner walls, pairs of rail gripping membershaving wedged engagement between the inclined walls of said bars,

and bolts extending through said bars for U simultaneously" securing the lattertogether and securing saidrail clamping members in lock-ed position between said bars. e 2. A railway tie comprising a pair of oppositely arrangedangle bars having oppositelyrinclined walls, .apair of rail gripping members at each end of said tie having wedged engagement between the oppositely inclined inner walls of said bars,the upper ends of the bars of the gripping members:

having suitable recesses to receive the base and adjacent portion of a rail, bolts secur-i 3. A railway tie comprising a pair of oppositely arranged angle bars having locked engagementythe upper faces of the bases of said bars being'oppositely inclined, pairs of rail gripping members adapted to receive portions'of the rails and contacting the upperfface of the bases of said angle bars at their opposite corners and providing securing the rails of a track to said members.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
